To all whom t may concern:

Be it known that I, FRANK B. Mums',l a

y citizen of the United States, anda resident of Oakland, county of `Alameda, State of 6 California, have inventeda newanduseful Casting Device for Type Metal, of which the following is a specification.

, The present inventionwrelateiswto improvc-y metal such e particular object of the invention is to provide means whereby type metal of any Adesired crosssection can be castin a continuous process.

A further object of the invention is to prof vide a device for this purpose that is exments inmeansv -for casting t trem'ely simple in constructlon and re uires' very little attentionV on the part o the operator. Further objects and .advantages of my invention will appear as the specification proceeds. y

' The preferred formof my invention is illustrated in the accompanying drawing, in

which Figure 1"shows a side elevation of `my device, with certain parts bemgshown in section, and Figure 2 a top plan view of the same-. A While I have shown vonl 1 the referred 4form of my invention, its ouldv be understood that variouschan es or modi-A 4ications may be made within t e scopey of the claims attached hereto`without departinfr from the spirit of' the invention.

invention comprises a vessel (1) adapte to be `filled with molten lead (2) having a V-shaped cylinder (3) supported therein 1n such a manner that its legs (4) and (6) project beyond ythe wall of the container as shown at (7) and (8) while the whole cylinder isslantin'gly sup rted so that its mouth (9) is substantia y on 'a level with the to lof theliquid. "metalL A mold (11)A coredpto present a cross-section of the desiredform threadedly f engages the upper end of the linder'so that the larger part of the mold is4 n orced through the same to cool o rapidly.

Each of thetwo legs '(4) and (6) Vof the" y 'my ing twodiscs (14) and (16) fxedto two shafts (17) and (18).supported in bearings (19) and (21) which two' discs receive rotary motion through beveled pinions (22) engaging :beveled ear (23) supportedou a' shaft The atter shaft may be rotated'in any suitable manner as for instance lcilylmeansfiof the two gears (26) and (27).v

-an intake. ort (31) having-a check valve 'Y (30) thereln, below the level of the liquid metal, andA a, lapvvalve ('32) is provided 'where the legs join to prevent back How of the liquid metal on the-rearwardstroke of each'plston.

At the' upper end of the mold are supported, in suitable brackets (33), two rollers (34) adaptedito engage the solid metal leaving the mold from opposite sides and to pull the same forward. .The rollers may be actuated from the shaft (24) by means of a chain (36) engagin sprockets (37) .and (38) on the shafts i tively,"the latter sha orming an integral part of one of the rollers (34). The other 85 '(39). through the two gear wheels (41) and l roller receives rotary motion from the shaft The operation ofthe device 7 may be described as follows: When the shaft k(24) isrotated, the two pistons (13) are reciprocated in their respective cylinder -le'gs in opposite directions. As oneof the pistons moves rearwardly it 1 draws the flap valve (32 toward its side and creates a vacum'whic vcauses the 1i uid-metal to enter-through the said leg. During the same stroke the other' piston moves forwardlyy port- (31) o and pushes a reviously collected amount of: liquid metal into the mold. 0n the next stroke the first piston moves forwardly andv ushes the amount of liquid vmetal recm'ved uring the rearward sti-fok'e into the mold" In this manner the tw stone coo rate in, eontmuousl 1 supply `o :molten metal into t eymold;` Allhilepassing through the mold the metalicools becomes solid, and

and (39) .'respecis ejected 'from the @chess-nd f they g1g;

mold in nished form. After reaching the two rollers (34:) the solid metal is engaged by the same and the rotation of the rollers forces the metal forward, thus assisting the action of the pistons. e I claim:

1. Means for casting type metal or 'theA4 like, comprising a vessel having molten y metal therein, a V-shaped cylinder submerged in the metal having a mold com-"f" municating with its base and having its two legs projecting beyond the outside of vthe cylinder and pumping means associated with each leg for causing a continuous flow of metal from the vessel into the mold.

2. Means forcasting type metal or the like, comprising a vessel having molten metal therein, a yVshaped vcylinder sub-l merged in the metal having a moldl communicating with its base and havi-ng its two legs projecting beyond the outside of the cylinder and pumping means associated with each leg for causing a continuous flow of metal from the vessel into the mold, consisting of pistons reciprocating in the legs in opposite directions.

3. Means for casting type metal or thef-livke comprisinga-"vessel 'Jhavmg molten metal therein, a mold supported so as to dip into the surface of the metal and pumping means associated with ,thewmold adapted to feed molten metal from the vessel into the mold. 4. Means for casting type metal or the like comprising a vesselrhaving molten metal therein, a mold slantingly supported relative to the surface of the metalwith its lower end dipping thereinto and pumping means associated with the mold adapted to feed molten metal from the vessel into the mold. 5. Means for casting type met-al or the like comprising a vessel having molten metal therein, a pump mechanism' supported in the wall of the vessel and made to draw on the metal and having an upwardly slanting discharge barrel and a mold secured to the end of the latter allowing molten metal to discharge thereinto.
